Measurement Systems & Controls - DM6400 Dynamic RAM

The DM and DMB series of boards were quite similar.  The DM did not have bank select capability, the DMB did.

The board consisted of 64K of dynamic RAM with refreshing independent of bus timing.  No wait states were required wit a 4MHZ Z80. The board was addressable in 4K increments at 4K boundaries.  The board utilized low power, fully loaded it used less than 8 watts. 

I do not have a manual for this board. If you can provide a copy or pdf file please let me know.
